1.	A small amount of quick lime is added to water in a beaker. (i) Name and define the type of reaction that has taken place. (ii) Write the balanced equation for the reaction and chemical names of the product formed. (iii) List two main observations in the reaction.
Answer» Solution :(i) It is combustion reaction - A reaction in which TWO or more elements or compounds is called COMBINATION reaction (ii) `CaO(s)+H_(2)O(l)toCa(OH)_(2)(aq)"CALCIUM hydroxide"`. (iii) OBSERVATION : (i) hissing sound is produced (ii) Solution becomes hot because heat is evolved.
